- An important objecty of the invention is to provide afdeviceof theabove kind which yis extremely simple and durable in construction aswell as highly'serviceable in use.

A still further object is to provide a dep vice of the above kind whichmaybe readily collapsed into compact form for requiring a minimum amountof space when not in use, eiiicient means .being provided for retainingthe parts in collapsed' relation.

Still anotherobject is to provide a` simple and desirable form of headrest for use when the device is in Creeper form, the head rest beingi'oldable out of the way when not for use, and means being provided toretain the head rest in foldedposition.

' Another vobject is to provide a. construction of the above kind inwhich thefolded head rest isv adapted *to engage the extensible section"of the platform to retain the latter in collapsed position.

Other objects will become apparent as the nature of lthe inventionisbetter understood A yand the same consists in the novelfform,combination, and arrangement of parts hereinafter more fully. described,shown in the accompanying drawings, and claimed.

In the drawings, wherein like reference characters indicateIcorresponding parts throughout the several views,

showing the device in extended condition to;

the platform Figure 1 is a top plan view of a' combined' Figure 5 is anenlarged longitudinal section taken upon line 5 5 vof Figure l,

Figure 6 is a view similar to Figure with. partly extended yand the headrest operatively disposed, 1 y

Figure 7 isa side elevationalk view of ythe device adjusted to form astool, and

Figure 8 Visan end elevational view looking towards the left in Figure1.

Referring more in detail to the drawings, the present invention includesa collapsible platform embodying a main section and an auxiliary section6 slidably and telescopically associatedwith the section 5 so as to'beshiftable longitudinally or the latter inextended or collapsed position.The main platform section 5 embodies a pair ofv spaced parallel siderails7 and a slatted flooror top wall including' alixed foot section 8`rigidly connecting the foot ends or the rails 7, a vertically swinginghead section 9 hinged as at 10 at its rear end to the rails 7, and atransverse slat or bar `11 `rigidly connecting the head ends of therails 7. The top wall or `floor sections embody transverse slatsconnected at their ends byk longitudinal strips 1Q, and these strips 12.of the hinged section 9 are adapted to extend across and rest upon thes'lat 11, while the latter carries a pivoted catch 13 adapted to beswung to a position for overlying the slat at thel'ree end of the hingedsection 9 to hold the latter in lowered operative position. The main`platiorm section 5 is provided at its corners with swiveled casters 14which promote the ease or movement of the device over the ground orlicor and which are mounted upon the ends of the side rails 7. f

The auxiliary or supplemental platform section 6 embodies a pair ofspaced parallel side rails l5 rigidly connected bycross slatsF 16 toform a top wall or iloor, the rails 15 being slida'bly guided inlongitudinal grooves 17 provided in the inner sides of the rails 7. Theplatform sections are of substantallyy equal length, and the movement of`the supplemental section 6 to collapsed position is limited by means ora suitable stop carried by the head end of the main section 5 andpreferably embodying an angle bracket 18 rhaving a horizontal ylegattached yto theslat 11 :and a vertical dependingleg arranged to beabutted by the intermediate one of a pluralityof spaced parallellongitudinal bars 19 arranged in spaced relation to and between the siderails 15 and rigidly secured at their ends upon transverse slats 2()fixed to the under side of the ends of the side rails 15, the bars 19extending beneath the transverse slats 16 as clearly shown in sev eralof the views. V

Arranged parallel with and at thel inner sides of the rails 15 as wellas pivoted atadjacent ends to the head ends'of said rails 15 as at 21,are a pair of supporting legs 22. Pivoted intermediate their ends as at23 to the intermediate portions of the legs 22 and arranged at the innersides of the latter is a further pair of legs 24, the adjacent ends ofwhich are respectively rigidly connected by transverse rods 25 and 26.Thus, with the platform collapsed, the legs may be extended in crossedrelation as shown in Figure 7 to form a stool, the upper ends of thellegs 24 being held against movement relative to the legs 22 at said timebyengagement of the lcross bar 26 in transversely alined transversegrooves 261L provided in the under sides kof the longitudinal bars 19.As shown, two sets of the grooves 26 are provided for selectivereceptionof the rod 25 whereby the height of the stool may be adjusted in anobvious manner. Further transverse grooves 27 and 28 are provided in theunder sides of the bars 19 at the ends ofthe latter for receiving therods 25 and 26 when the legs arein collapsed condition iatly disposed atthe under sides of the slats 16 and at the inner sides of the rails 15.The grooves 23 are preferably undercut as clearly shown in Figures 4l,5, and 6, and in order to hold the legs in collapsed position, suitablecatches 29 are pivoted to the underside of the outer ones of the bars 19and are engageable under keeper plates 30 fastened to the under side ofthe rails 15.

-V .KMounted on the under side ofthe trans verse slats 2O at the footend of the platform section 6 intermediate the sides of the latter,

is a swiveled caster 3l which promotes ease of movement of the section 6with the section 5 over the floor, as well as ease of movement of thesection 6 to and from collapsed position. Suitable inwardly projectingstop members 32 are fixed Vto the under side of the side rails 7 nearthe foot ends of the latter, so that the inwardly projecting ends ofthese stop members 32 are arranged in the path of the transverse slat 2Oat the head end of the auxiliary or foot section 6 of the platform,whereby the movement of the section 6 to extended position is properlylimited.

The device further embodies arfoldable head rest including a. pair ofarms or posts 33 pivot-ed at corresponding ends as at v34 to the outersides of the rails 7 near the head end of the latter and having theirother free ends rigidly connected by a cross bar 35. Attached to thecross slat 11 at one end is j withdrawin a fabric sheet 36 whose otherlend is attached to the bar 35so that when the arms 33 are swung to arearwardly and upwardly 1nclined position, said sheet 36 will be placedin a taut conditiony to form a flexible or yielding support for the headof the person lying in a'pro'ne position upon the Creeper. The arms 33are adapted to be swung forwardly and downwardly to assume a positionalongside the rails 7 and to position the cross bar 35 between a pairrofthe slats 16 when' the platform is collapsed, thereby holding theplatform section 6 from' being extended unless the arms33 are raised todisengage the'bar 35 from between said slats 16. The downwardfmo'vementof the arms 33 and passage of bar 35 and the sheet 36 beneath the hingedfloorrsection 9 is permit ted by swinging the latter upwardly on thehinges 10. When the head rest is thus folded it is neatly disposed outof the Way, and with the catch 13 engaging the Hoor section 9, the bar35 will be held between the adjacent. pair of slats 16 to edectivelyprevent extension of the platform section 6. The upward swingingmovement ofthe arms 33, to voperatively position the head rest, maybeproperly llimited by lateral pins 37 provided on the outer sides of therailsv 7 and engageable by stop lugs38 on the pivoted ends' of the arms33.

When it is desired to Iuse the device as a. creeper, the floor section 9is raised so as to permit the head rest to be swung tooperaytiveposition and at the same time release they lfoot section 6 ofthe platform. The foot section 6 is thenwithdrawn or extended, and withthe floor section 9 again lowered and held by the catch 13, the deviceis ready for use. A reversal ofthis operation will collapse the devicefor requiringa minimum amount of space when not in use, and Vwhen socollapsed, the device maybe j converted into a stool by simply`disengaging the catches 29 from the keeper plates 30 and the legs 22andj24 from the folded position between the'rails 15 as `shown 1n Figure4 to the unfolded position: of Figuref7, the rod 25,'1beingengaged inthe proper set of 4grooves 26n in accordance with the height kdesiredfor the stool.` l

VMinor changes may be made without departing from the spirit and scopeof the invention as claimed.

What Iclaim as new is: l

1. In an automobile repairmaiis Creeper, a shiftable platform embodyinga main section and an. auxiliary section slidably telescopicallyassociated with said inainsection for movement longitudinally of 'thelatter yto extended or collapsed position, said main foldable beneathsaid hinged floor section, said y head rest embodying a memberengageable with the-auxiliary section to hold it in co1- lapsedposition.

2. In an automobile repairmans Creeper, a shiftahle platform embodying amain seotion and an auxiliary section slidably telesoopioally associatedWith said main section for movement longitudinally of the latter toextended or collapsed position, said main section having a hinged floorsection, and a 10 head rest carried by said main section and foldablebeneath said hinged oor section, said head rest embodying a memberengageable with the auxiliary section to hold it in collapsed position,and means to retain the hinged Hoor section in lowered nosition tosecure the head rest in engagement With the auxiliary seotion.-

In testimony whereof I aix my signature.
